Blocking a signal that attracts pathogenic T cells to the brain’s lymphatic vessels could help treat multiple sclerosis, according to a Nature Neuroscience study. The findings add MS to a short but growing list of CNS disorders in which the recently discovered cerebral vessels are implicated.

Until three years ago, neuroscientists believed the brain, unlike the rest of the body, did not contain lymphatic vessels....
